Abstract: In cooling mode, the temperature dependence of the heat capacity and changes in the thermodynamic functions of aluminum alloy $\rm AlFe5\rm Si10$ with tin in the temperature range of $300$–$800$ K were studied. It is shown that with an increase in tin concentration, the heat capacity and heat transfer coefficient of aluminum alloy $\rm AlFe5\rm Si10$ decrease, and with an increase in temperature, they increase. It has been established that with increasing temperature, the enthalpy and entropy of the alloys increase and the Gibbs energy decreases, and with an increase in the tin content in the alloy, the inverse relationship is observed.
